Note
• After invoking the commands CMGW, CMGS or CMGC it is nec-
essary to wait for the ">" symbol before entering text or PDU.
• At baudrates below 19200 it is recommended to use the line
termination character only (refer to +ATS3, default , pg. 25)
before entering the text/pdu. Use of the line termination charac-
ter followed by the response formating character (refer to +ATS4,
default , pg. 25) can cause problems.
